Spectacular aerial footage of a three-day feeding frenzy has been captured off the coast of Western Australia, with over 30 sharks tearing into a whale carcass. While on a fishing trip, father and son Grant and Sam Eastland captured footage on July 4 of a school of, what they believe to be , tiger sharks feasting on a dead whale. They told 7 News the sharks were there for three days.Around the three-minute mark, the carcass makes it to shore with many of the sharks following suit. At one point, one of the sharks ends up on land on its back, as it begins thrashing to get back in the ocean. The son even gets close enough to touch its tail. Credit: Imagery from Above
